AbstractUniaxial compressive strength (UCS) has become a highly essential strength parameter in the mining, civil and geomechanical industries. Estimating the exact value of the strength of rock has become a matter of great concern in real life. Despite this, there have been many works to indirectly/directly estimate the UCS of rocks. This study introduces a novel ...... hiện toàn bộ
Tóm tắtKhi các vật liệu khai thác tự nhiên ngày càng hiếm và kinh tế, ngành xây dựng đã chuyển sang các lựa chọn bền vững như chất thải xây dựng và phá dỡ (C&D) và kính tái chế cho xây dựng đường. Mục tiêu của nghiên cứu này là đánh giá hiệu suất của các hỗn hợp bao gồm kính tái chế (RG), gạch nghiền (CB) và cốt liệu bê tông tái chế (RCA) dưới các điều kiện gia...... hiện toàn bộ

Efforts to reduce the weight of buildings and structures, counteract the seismic threat to human life, and cut down on construction expenses are widespread. A strategy employed to address these challenges involves the adoption of foam concrete. Unlike traditional concrete, foam concrete maintains the standard concrete composition but excludes coarse aggregates, substituting them with a foam agent....... hiện toàn bộ

The frequent occurrence of building collapse accidents not only causes significant casualties, but also jeopardizes local economies. This paper adopts a combinatory assessment approach to showcase the lessons learned from a recent building collapse in Changsha, China. The proposed approach blends the system thinking approach and strategic environmental assessment (SEA) model. It delineates the cau...... hiện toàn bộ
The creation of smart cities has benefited greatly from the quick advancement of sensor and actuator technology. The basis of data-driven urban environments is supported by these technologies, which seamlessly connect with the Internet of Things (IoT). This in-depth review paper explores the crucial part that sensors and actuators play in the development of smart cities, covering important topics ...... hiện toàn bộ
Waterlogging in subway stations has a devastating impact on normal operation of important urban facilities and can cause harm to passengers and property. It is difficult to assess the vulnerability of metro stations to waterlogging because many complex factors are involved. This study proposes a hybrid model to assess the vulnerability of subway stations to waterlogging by integrating the entropy ...... hiện toàn bộ
Wind-driven sand erosion is the leading primary reason of earth deterioration in dry lands and a major global issue. Desert dust emissions and topsoil degradation caused by wind pose a global danger to the ecosystem, economy, and individual health. The aim of the current study is to critically analyze the different types of biopolymers and their interaction mechanism with sands for desert sand sta...... hiện toàn bộ
